Moving a card from one Trello board to another has been implemented recently but I am still missing some basic "duplicate card" functionality. Is it possible to duplicate or clone a card on the same board as its original?

In my use case for some software development, I would like some sub-functionalities (listed in a card checklist) stay in my project backlog while others on the same card are brought to the next step toward life.

I am not asking for some split function inside Trello, which I guess would be relatively heavy to implement. Duplicate function would be convenient enough, as I would just have to delete checklist elements according to my reorganization instead of (currently) having to manually clone the card and all information inside.

Good news! The "copy/clone/ template boards, lists, cards, and checklists" card is in the 'Next Up' "In Progress" column on the public Trello development board, https://trello.com/c/LIqasVwP; please vote it up, work ought to start on it soon!
